I'm a bit confused, clarification on some items:
1. If I buy the one way Haruka + Icoca for Y3000, how much will be my Icoca load that I can use the following days/weeks?
2. Haruka return pass can only be used in Haruka line right? So if I'll be coming from Namba, return pass is not advisable?
3. Haruka + Icoca is only for foreign travelers, I can buy this set at the airport right? Not like JR Pass that should be bought before going to Japan?
4. Can I use Icoca in Tokyo?
